2019-07-25drm/tinydrm: Rename variable mipi -> dbiNoralf Trønnes1-10/+10
struct mipi_dbi is going to be split into an interface part and a display pipeline part. The interface part can be used by drivers that need to initialize the controller, but that won't upload the framebuffer over this interface. tinydrm uses the variable name 'mipi' but this is not a good name since MIPI refers to a lot of standards. This patch changes the variable name to 'dbi' where it refers to the interface part of struct mipi_dbi. Functions that use both future parts will have both variables temporarily pointing to the same structure.

2019-07-23drm/tinydrm: Move tinydrm_display_pipe_init() to mipi-dbiNoralf Trønnes2-27/+10
tinydrm_display_pipe_init() has only one user now, so move it to mipi-dbi. Changes: - Remove drm_connector_helper_funcs.detect, it's always connected. - Store the connector and mode in mipi_dbi instead of it's own struct. Otherwise remove some leftover tinydrm-helpers.h inclusions.

2019-07-23drm/tinydrm/mipi-dbi: Add mipi_dbi_init_with_formats()Noralf Trønnes1-0/+5
The MIPI DBI standard support more pixel formats than what this helper supports. Add an init function that lets the driver use different format(s). This avoids open coding mipi_dbi_init() in st7586. st7586 sets preferred_depth but this is not necessary since it only supports one format. v2: Forgot to remove the mipi->rotation assignment in st7586, mipi_dbi_init_with_formats() handles it.

2019-07-23drm/tinydrm: Move tinydrm_spi_transfer()Noralf Trønnes2-5/+3
This is only used by mipi-dbi drivers so move it there. The reason this isn't moved to the SPI subsystem is that it will in a later patch pass a dummy rx buffer for SPI controllers that need this. Low memory boards (64MB) can run into a problem allocating such a "large" contiguous buffer on every transfer after a long up time. This leaves a very specific use case, so we'll keep the function here. mipi-dbi will first go through a refactoring though, before this will be done. Remove SPI todo entry now that we're done with the tinydrm.ko SPI code. v2: Drop moving the mipi_dbi_spi_init() declaration (Sam) Cc: David Lechner <david@lechnology.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: : David Lechner <david@lechnology.com> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190719155916.62465-8-noralf@tronnes.org
2019-07-23drm/tinydrm: Clean up tinydrm_spi_transfer()Noralf Trønnes1-2/+1
Prep work before moving the function to mipi-dbi. tinydrm_spi_transfer() was made to support one class of drivers in drivers/staging/fbtft that has not been converted to DRM yet, so strip away the unused functionality: - Start byte (header) is not used. - No driver relies on the automatic 16-bit byte swapping on little endian machines with SPI controllers only supporting 8 bits per word. Other changes: - No need to initialize ret - No need for the WARN since mipi-dbi only uses 8 and 16 bpw. - Use spi_message_init_with_transfers() Cc: David Lechner <david@lechnology.com> Acked-by: : David Lechner <david@lechnology.com> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190719155916.62465-7-noralf@tronnes.org
2019-07-23drm/tinydrm: Remove tinydrm_spi_max_transfer_size()Noralf Trønnes1-1/+0
spi-bcm2835 can handle >64kB buffers now so there is no need to check ->max_dma_len. The tinydrm_spi_max_transfer_size() max_len argument is not used by any callers, so not needed. Then we have the spi_max module parameter. It was added because staging/fbtft has support for it and there was a report that someone used it to set a small buffer size to avoid popping on a USB soundcard on a Raspberry Pi. In hindsight it shouldn't have been added, I should have waited for it to become a problem first. I don't know it anyone is actually using it, but since tinydrm_spi_transfer() is being moved to mipi-dbi, I'm taking the opportunity to remove it. I'll add it back to mipi-dbi if someone complains. With that out of the way, spi_max_transfer_size() can be used instead. The chosen 16kB buffer size for Type C Option 1 (9-bit) interface is somewhat arbitrary, but a bigger buffer will have a miniscule impact on transfer speed, so it's probably fine.

2019-07-09drm/client: Support unmapping of DRM client buffersThomas Zimmermann1-0/+2
DRM clients, such as the fbdev emulation, have their buffer objects mapped by default. Mapping a buffer implicitly prevents its relocation. Hence, the buffer may permanently consume video memory while it's allocated. This is a problem for drivers of low-memory devices, such as ast, mgag200 or older framebuffer hardware, which will then not have enough memory to display other content (e.g., X11). This patch introduces drm_client_buffer_vmap() and _vunmap(). Internal DRM clients can use these functions to unmap and remap buffer objects as needed. There's no reference counting for vmap operations. Callers are expected to either keep buffers mapped (as it is now), or call vmap and vunmap in pairs around code that accesses the mapped memory. v2: * remove several duplicated NULL-pointer checks v3: * style and typo fixes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/315831/

2019-06-25drm/edid: parse CEA blocks embedded in DisplayIDAndres Rodriguez1-0/+10
DisplayID blocks allow embedding of CEA blocks. The payloads are identical to traditional top level CEA extension blocks, but the header is slightly different. This change allows the CEA parser to find a CEA block inside a DisplayID block. Additionally, it adds support for parsing the embedded CTA header. No further changes are necessary due to payload parity. This change fixes audio support for the Valve Index HMD.

2019-06-21drm/ioctl: Ditch DRM_UNLOCKED except for the legacy vblank ioctlDaniel Vetter1-0/+3
This completes Emil's series of removing DRM_UNLOCKED from modern drivers. It's entirely cargo-culted since we ignore it on non-DRIVER_LEGACY drivers since: commit ea487835e8876abf7ad909636e308c801a2bcda6 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Sep 28 21:42:40 2015 +0200 drm: Enforce unlocked ioctl operation for kms driver ioctls Now justifying why we can do this for legacy drives too (and hence close the source of all the bogus copypasting) is a bit more involved. DRM_UNLOCKED was introduced in: commit ed8b67040965e4fe695db333d5914e18ea5f146f Author: Arnd Bergmann <arnd@arndb.de> Date: Wed Dec 16 22:17:09 2009 +0000 drm: convert drm_ioctl to unlocked_ioctl As a immediate hack to keep i810 happy, which would have deadlocked without this trickery. The old BKL is automatically dropped in schedule(), and hence the i810 vs. mmap_sem deadlock didn't actually cause a real deadlock. But with a mutex it would. The solution was to annotate these as DRM_UNLOCKED and mark i810 unsafe on SMP machines. This conversion caused a regression, because unlike the BKL a mutex isn't dropped over schedule (that thing again), which caused a vblank wait in one thread to block the entire desktop and all its apps. Back then we did vblank scheduling by blocking in the client, awesome isn't it. This was fixed quickly in (ok not so quickly, took 2 years): commit 8f4ff2b06afcd6f151868474a432c603057eaf56 Author: Ilija Hadzic <ihadzic@research.bell-labs.com> Date: Mon Oct 31 17:46:18 2011 -0400 drm: do not sleep on vblank while holding a mutex All the other DRM_UNLOCKED annotations for all the core ioctls was work to reach finer-grained locking for modern drivers. This took years, and culminated in: commit fdd5b877e9ebc2029e1373b4a3cd057329a9ab7a Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sat Dec 10 22:52:54 2016 +0100 drm: Enforce BKL-less ioctls for modern drivers DRM_UNLOCKED was never required by any legacy drivers, except for the vblank_wait IOCTL. Therefore we will not regress these old drivers by going back to where we've been in 2011. For all modern drivers nothing will change. To make this perfectly clear, also add a comment to DRM_UNLOCKED. v2: Don't forget about drm_ioc32.c (Michel).

2019-06-21drm/prime: Update docsDaniel Vetter2-20/+102
Yes this is a bit a big patch, but since it's essentially a complete rewrite of all the prime docs I didn't see how to better split it up. Changes: - Consistently point to drm_gem_object_funcs as the preferred hooks, where applicable. - Document all the hooks in &drm_driver that lacked kerneldoc. - Completely new overview section, which now also includes the cleaned up lifetime/reference counting subchapter. I also mentioned the weak references in there due to the lookup caches. - Completely rewritten helper intro section, highlight the import/export related functionality. - Polish for all the functions and more cross references. I also sprinkled a bunch of todos all over. Most important: 0 code changes in here. The cleanup motivated by reading and improving all this will follow later on. v2: Actually update the prime helper docs. Plus add a few FIXMEs that I won't address right away in subsequent cleanup patches. v3: - Split out the function moving. This patch is now exclusively documentation changes. - Typos and nits (Sam). v4: Polish suggestions from Noralf.
